A Comparative Study Of Perceptions Of High School Department Chairs And High School Teachers On The Role Of The High School Academic Department Chair: The Voice Of The Teacher-Department Chair, Rachel Mae Korach

Dissertations and Theses

The purpose of this descriptive study was to examine and compare perceptions between high school department chairs and teachers regarding the role of the high school academic department chair in Oregon, a position which has been largely ignored in recent educational reform efforts. Schools selected for the study were limited to those sharing the same qualities of size and structure as those of the high schools in the researcher's own district. A researcher-constructed questionnaire defining 44 activities comprising five categories of department chair responsibility provided data from 118 high school department chairs and 114 teachers from 34 Oregon high schools. …

Validity, Reliability, And Utility Of The Oregon Assessment For 3-5 Year Olds In Developmentally Appropriate Classrooms, Steffen Saifer

Dissertations and Theses

An early childhood assessment tool was developed by the author to fill a need for an observational, authentic, child assessment instrument that would include the measurement of social and emotional development, help guide teachers towards best curriculum practices, and meet common criteria for effective, appropriate, and equitable assessment. Theoretical constructs of interactionalism, multiple intelligences, dispositions, and developmentally appropriate practices were used to inform the construction of the tool. In addition, the author hoped to develop a tool that would be effective for use as a Head Start program evaluation research instrument. Research methods involved a representative random sample of 200 …

Unrelated Business Enterprise And Unfair Business Competition Issues Facing Nonprofit Organizations, Larry Glen Scruggs

Dissertations and Theses

Unrelated business enterprises have been an appropriate way for nonprofit organizations to generate income since the first income tax was enacted into law. The Internal Revenue Act of 1950 clarified this opportunity and enacted the Unrelated Business Income Tax to ensure that fair competition existed between nonprofits and for profit organizations. Nonprofit organizations conducting unrelated business enterprises are faced with a dilemma: it is legal for them to conduct such enterprises but if they do so they face potential litigation from for profit business for unfair competition and/or potential loss of tax-exempt status for operating outside of their exempt function. …

A Salinger-Ized Socrates, Jodi Geren

Anthós Journal (1990-1996)

Throughout the Gorgias, Plato returns to irony to color the characters in their plights of ambiguity and inability. Present in nearly every layer and language form operating within the work, irony is perhaps the greatest contributing factor to the modernist and timeless tone of the dialogue. Using this technique, Plato is able to layer antagonism, infer implication, and make every character seem slightly out of his element, thus provoking an awkward, but seemingly necessary situation. This paper portrays Socrates as the anti-hero, the ancient Holden Caulfield.

A Hermeneutic Reading Of Natalie Barney And Renee Vivien, Antoinette Sherman

Anthós Journal (1990-1996)

Traditional representational discourses have constructed others within Europe-women, homosexuals, the insane-as well as others external to Europe. As two lesbian women born at the turn of the century, Natalie Barney and Renee Vivien were the traditional other to their native land. In response to this, each chose expatriation and made France her permanent home, where they created a working and living relationship that would last for nearly fifteen years. Leaving one's world and culture behind, voluntarily or involuntarily, means engaging oneself in a complex process of composing one's identity and otherness. For Natalie Barney and Renee Vivien, French language and …

Clinging To Life: Varecia Variegata Rubra And The Masoala Coastal Forests, Natalie Vasey

Anthropology Faculty Publications and Presentations

The article describes the authors field study from October 1993 to February 1995 in Madagascar, surveying coastal and riverine forests, villages, and watersheds, studying the ecology and behavior of Varecia varuegata rubra, the red ruffed lemur, and Lemur fulvus albifrons, the white fronted lemur.

Scenery As Policy: Public Involvement In Developing A Management Plan For The Scenic Resources Of The Columbia River Gorge, Gordon Mathews Euler

Dissertations and Theses

The Columbia River Gorge National Scenic Area (NSA) was created in 1986 in response to a growing interest in preserving the scenic beauty of the gorge. The creation of the NSA and other areas around the country with a scenic resource emphasis indicates a growing interest in protecting landscapes with diverse scenic qualities that are not showcase areas such as the Grand Canyon and Yosemite. NSA mandates included the protection and enhancement of scenic, natural, cultural, and recreational resources (SNCRs) as the primary concern in the consideration of new land uses. The NSA management plan contains a complex mix of …

Determining The Factors Influential In The Validation Of Computer-Based Problem Solving Systems, Leslie Anne Morehead

Dissertations and Theses

Examination of the literature on methodologies for verifying and validating complex computer-based Problem Solving Systems led to a general hypothesis that there exist measurable features of systems that are correlated with the best testing methods for those systems. Three features (Technical Complexity, Human Involvement, and Observability) were selected as the basis of the current study. A survey of systems currently operating in over a dozen countries explored relationships between these system features, test methods, and the degree to which systems were considered valid. Analysis of the data revealed that certain system features and certain test methods are indeed related to …

Value Measurement For New Product Category: A Conjoint Approach To Eliciting Value Structure, Roland Helmut Heger

Dissertations and Theses

Ability to measure value from the customer's point of view is central to the determination of market offerings: Customers will only buy the equivalent of perceived value, and companies can only offer benefits that cost less to provide than customers are willing to pay. Conjoint analysis is the most popular individual-level value measurement method to determine relative impact of product or service attributes on preferences and other dependent variables. This research focuses on how value measurement can be made more accurate and more reliable by measuring the relative influence of selected methodological variations on performance in prediction and on stability …

Lewis And Clark On The Columbia River: The Power Of Landscape In The Exploration Experience, William L. Lang

History Faculty Publications and Presentations

During their 1804-06 transcontinental expedition, Meriwether Lewis and William Clark expected that the Columbia River and its tributaries would provide relatively easy passage to the Pacific Coast. Instead, they encountered a formidable barrier of raging waters and disjunctive ecological zones. Continuous frustrations caused the explorers to offer harsh judgments of the landscape and some of the Indians, whom they labeled as primitive and treacherous. These descriptions contrasted greatly with their more positive portrayals of landscape and peoples encountered elsewhere during the trip.

Wapato For The People : An Ecological Approach To Understanding The Native American Use Of Sagittaria Latifolia On The Lower Columbia River, Melissa Cole Darby

Dissertations and Theses

Sagittaria latifolia Willd. was an important root food and trade commodity for the Indians who lived along the Lower Columbia River in early historic times. This plant was prolific in the extensive wetlands of the Lower Columbia from about the great Cascades to the Kalama River. The tubers of this plant were called "wapato" in Chinook Jargon, the local trade language. The wetlands, and this plant that grew there, occupied a vast extent of the Lower Columbia territory; so much so that this valley was named 'Wapato Valley' by Lewis and Clark in 1805. This thesis will provide pertinent information …

Simple Approximation For Thermal Diffusion In Ionized Gas Mixtures, John D. Ramshaw

Physics Faculty Publications and Presentations

A simple approximation for thermal diffusion in gas mixtures was recently proposed [1]. This approximation was based upon relations valid for rigid spheres. It is therefore appropriate for molecules with steep repulsive potentials, but not for ionized species interacting via the Coulomb potential. Here we formulate an analogous approximation for ionized species and free electrons. The resulting thermal diffusion coefficients differ in sign from those for hard molecules.

Friction-Weighted Self-Consistent Effective Binary Diffusion Approximation, John D. Ramshaw, C. H. Chang

Physics Faculty Publications and Presentations

The self-consistent effective binary diffusion (SCEBD) approximation for multicomponent diffusion in gas mixtures is reconsidered and reformulated. The new formulation is based on the fact that a suitable rearrangement of the Stefan-Maxwell equations provides an exact expression for the complementary mean velocity a_i for species i as a weighted average of the velocities of all the other species. The coefficients in a_i are normalized friction coefficients which are simply related to the true binary diffusion coefficients. A simple factorized bilinear approximation to the friction coefficients then yields approximate species diffusion fluxes identical in form to those of a …

Where Have All The Ideophones Gone? The Death Of A Word Category In Zulu, George Tucker Childs

Applied Linguistics Faculty Publications and Presentations

The first step in the discussion is to demonstrate that ideophones constitute a word class, a relatively uncontroversial claim for Southern Bantu. The second is to show that native speakers of Zulu do not share equal knowledge of ideophones and how this knowledge correlates with social factors. Measured knowledge of ideophones is evaluated against the social factors of age, sex, education, residence patterns, and rusticity, a parameter to be elaborated below. The conclusion is that just as for pidgins and creoles (Childs 1994) the knowledge and use of ideophones serves as a reliable barometer for language typing and language change, …

Global Optimization Studies On The 1-D Phase Problem, Martin Zwick, Byrne Elliot Lovell, Jim Marsh

Complex Systems Faculty Publications and Presentations

The Genetic Algorithm (GA) and Simulated Annealing (SA), two techniques for global optimization, were applied to a reduced (simplified) form of the phase problem (RPP) in computational crystallography. Results were compared with those of "enhanced pair flipping" (EPF), a more elaborate problem-specific algorithm incorporating local and global searches. Not surprisingly, EPF did better than the GA or SA approaches, but the existence of GA and SA techniques more advanced than those used in this study suggest that these techniques still hold promise for phase problem applications. The RPP is, furthermore, an excellent test problem for such global optimization methods.

Reducing Waste During Logging And Log Processing: Forest Conservation In Eastern Amazonia, Jeffrey J. Gerwing, Jennifer S. Johns, Edson Vidal

Environmental Science and Management Faculty Publications and Presentations

This article describes the waste associated with logging and log processing in eastern Amazonia and suggests methods for reducing both waste and forest damage as a result of logging.

Salesforce Involvement In New Product Predevelopment Activities Of High Technology Firms, Candace Petersen

Dissertations and Theses

The strongest correlate of new product success is understanding of market requirements early in the new product development (NPD) process. This is true in high technology environments where rapid change and chaotic market conditions prevail. Although a firm's salesforce is viewed as one of many sources of new product ideas and market information, the involvement of salespeople in NPD activities varies widely across firms. This study examines salesforce involvement in a firm's NPD predevelopment activities, i.e. idea generation and screening, preliminary market assessment, and concept evaluation. Because of the limits of existing research in this area, a two-phase research design …

Jitter And Wander Reduction For A Sonet Ds3 Desynchronizer Using Predictive Fuzzy Control, Kevin Blythe Stanton

Dissertations and Theses

Excessive high-frequency jitter or low-frequency wander can create problems within synchronous transmission systems and must be kept within limits to ensure reliable network operation. The emerging Synchronous Optical NETwork (SONET) introduces additional challenges for jitter and wander attenuation equipment (called desynchronizers) when used to carry payloads from the existing Plesiochronous Digital Hierarchy (PDH), such as the DS3. The difficulty is primarily due to the large phase transients resulting from the pointer-based justification technique employed by SONET (called Pointer Justification Events or PJEs). While some previous desynchronization techniques consider the buffer level in their control actions, none has explicitly considered wander …

A Methodology For Regional Seismic Damage Assessment And Retrofit Planning For Existing Buildings, Thomas C. Mccormack

Dissertations and Theses

Recent geologic research has shown that earthquakes more destructive than formerly expected are likely to occur in the Pacific Northwest. To mitigate catastrophic loss, planners are gathering information to make decision on implementing regional seismic retrofit programs. This research develops a model to estimate regional earthquake losses for existing buildings, and determine optimal retrofit priorities and budgets. Fragility curves are developed to provide earthquake damage estimates for a range of seismic intensities. The published earthquake damage estimates of a large group of prominent earthquake engineering experts are extended to include the combined effect of structure type, earthquake-sensitive variations in building …

Characteristics Of Administrators' Leadership Style In Quality Child Care Centers, Katherine Ann Bobula

Dissertations and Theses

The utilization of center-based child care services by working and student parents has increased dramatically over the last two decades, and has been accompanied by an equally strong interest, among the public and researchers alike, in the establishment and maintenance of quality caregiving in center-based care. This study addresses the leadership characteristics of administrators of quality child care centers. The intent of the study is to add to the existing knowledge concerning the role that the child care center administrator has in maintaining the delivery of high quality child care by the teaching-caregiving staff. Two factors were investigated: the leadership …

Connection, Service And Community: An Examination Of Factors That Contribute To Student And Staff Success, Robert Vieira

Dissertations and Theses

This study examined the general hypothesis that student interactions with front line staff members in higher education settings have a positive impact upon student experiences, and ultimately, their persistence in colleges and universities. This study also examined the reciprocal hypothesis that this same interaction has a positive impact upon staff job satisfaction and service quality. Several bodies of literature were reviewed as a framework for the examination of these questions, including student persistence and related factors, job satisfaction, total quality management and service quality. A quasi- experimental research design was employed to examine an intervention linking new freshmen with individual …

Impact Of The Medical Library Assistance Act Of 1965 On Health Sciences Libraries In The Pacific Northwest: An Interorganizational Approach, Leonoor Swets Ingraham

Dissertations and Theses

Since the 1960's, the number of publications has increased at a phenomenal rate, and the introduction of the computer has resulted in greatly expanded technological advances in information processing and information access. The information delivery component of health sciences libraries has been transformed; and concomitantly, their interorganizational relations have been altered. This research investigates the impact of a federally mandated information program. The Medical Library Assistance Act was passed in 1965 to support the escalating information needs of health professionals. Also, a computerized access system for biomedical literature was introduced by the National Library of Medicine. This study focuses on …

The Relationship Between A Pre-Departure Training Program And Its Participants' Intercultural Communication Competence, Daniel Timothy Ferguson

Dissertations and Theses

Self-reported behaviorally-based intercultural communication competence inventories are one way to understand the relationship between a pre-departure training program and its participants' intercultural communication competence (ICC). One such inventory, called the Cross- Cultural Adaptability Inventory (CCAI), was chosen to explore this relationship.

This research sought to confirm or reject the following three hypotheses: 1) experimental subjects will demonstrate higher levels of ICC than control subjects, 2) experimental subjects will demonstrate higher levels of ICC after they take the pre-departure class at Walla Walla College, and 3) there will be relationships among all subjects' ICC and the demographic variables involved in this …

A Policy-Independent Secure X Server, Kirk Joseph Bittler

Dissertations and Theses

This thesis demonstrates that a secure X system can be designed and implemented to be independent of a particular security policy. The advantages and costs of a separation of security policy and enforcement are examined by developing a large scale application, the DX windowing system, on a DTOS platform. DTOS is a high assurance operating system that isolates policy decisions in a Security Server. A security conscious process, such as DX, eliminates policy considerations from the code. The process instead consults the Security Server and enforces the decisions that server derives from the policy. The DX architecture is described and …

Embedded Particle Computation In Evolved Cellular Automata, Wim Hordijk, James P. Crutchfield, Melanie Mitchell

Computer Science Faculty Publications and Presentations

In our work we are studying how genetic algorithms (GAs) can evolve cellular automata (CAs) to perform computations that require global coordination. The evolving cellular automata" framework is an idealized means for studying how evolution (natural or computational) can create systems that perform emergent computation, in which the actions of simple components with local information and communication give rise to coordinated global information processing [3].

In previous work [4, 5], we analyzed the process by which a genetic algorithm designed CAs to perform particular tasks. In this paper we focus on how these CAs implement the emergent computational strategies for …
